Application fled Kay 4,

To all whom it may concern:

.Be it known that I, WILLIE O. BESAW,

a citizen of the United States, residing at Beedley, in the county of Fresno and State .of California, have invented certain new it is my purpose to provide a fuse elementthat may be inserted into the usual sockets of the fuse boxes of house wire systems in conjunction with a burnt'out fuse plug for again completing the circuit between the terminal wires of the wiring system, the primary object of the invention being the provision of such a fuse element that is extremely simple of construction, and one that may be manufactured and marketed at substantially one-tenth or more of the cost of the usual fuse plugs now universally used.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of thisapplication, like numerals of reference indicate similarparts in the several views, and wherein:

Figure 1 is'fa side elevation of my improved fuse element, the same being shown in position within a socket of a fuse box, and maintained therein through the medium of a burnt out well known form of fuse plug.

Figure 2 is a plan view of my fuse elemrfit per se, and

igure 3 is a detail longitudinal cross section upon the line 3-3 of Figure 2.

Referring to the drawing, and larly to Figure 1, 5 indicates a soc et element of the usual insulating material provided with an internal metallic lining 6, as well as a contact element 7 insulated from the lining 6, this contact element and lining being of course in circuit with the feed and neutral wire respectively, of the house wiring system. Also in this figure, 8 indicates a fuse plu of conventional form, it being of course un erstood-that the socket element 5 and plug 8 :do not constitute any portion 0 my invention, the

same being. merely shown for permitting .of the more adequate disclosure of the relationshipof my invention therewith. My fuse element per se,-designated generally 9 is in the form of a disk of'a diameter equivalent to the internal diameter of the lining 6 of the socket meniber 5. This fuse element comprises a pair of disks 10 and 11 of mica, or other noninsulating material, between which is a length of fusible wire. 12 preferably of serpentine shape. One end of this fusible Wire 12 is extended around the central portion of a lead rivet 13 that serves as a connecting means for the pair of disks 10 and 11. Surrounding the edges of these disks 10 and 11 is a clamped ring 14 of some suitable shaped metal.

In practice, when one of the usual fuse plugs 8 of the house wiring system is burnt out, the same is removed from the socket member 5, and my fuse element positioned therein as shown in Figure 1. One side of the lead rivet 13 will engage the contact 7 of the socket element 5, while the ring 14 will have close contact with the adjacent portion of the plug lining 6. After the fuse element has been positioned within the socket, the burnt out plug is again inserted therein, and serves as a means for maintaining my fuse element in proper position within the-socket. It will of course be understood that the usual contact upon the lower end of the plug 8 will engage the oppositeend of the rivet 13 for thereby completing the circuit between the contact 7 and liningfi. Any overload upon the line will occasion a burning out of the fusible wire 12, after which the plug 8 may be removed as well as the fuse element, and another fuse element positioned in its stead.

provided what I claim as new, and desire to secure by Letters-Patent, is: f. 7 y

1. In combination with a socket element anda, burnt out fuse plug, a wire adapted-- to bepositioned within the socket and maintained therein b said burnt out fuse plug,

the opposite en s of the wire being in cir-V cuit with the usual contact element lining of said socket element.

2. n combination with a socket element and and burnt out fuse plu means adapted for burnt out fuse plug, said'disk including a l fusible wire and means for contactingthe ends of saidfusible' 'wirelwith the usual contacts of said socket element.

4.- A fuse comprising a pair of discal insulating members, a circularv conductor Iperipherally holding the insulating 'mem ers together, a conductor member passing concentrically through the discs, and a fusible member passing between the discs to connect the conductors.

5. A fuse comprising an annular conductor adapted to engage the outer wall of a socket, a pair of insulating discs supported bythe annulus, a contact member concentric of the discs, and a fusible wire between *the discs electrically connecting the disc with the annulus.
